SANDOVAL, Sindy; VILLORIN, Tulio  e  GONZALEZ, Margarita. Study of the efficiency of an algal fertilizer from Caulerpa sertularoides species compared to a commercial chemical and natural fertilizer, using a culture of Coriandrum sativum . Revista de Investigación [online]. 2017, vol.41, n.90, pp.083-101. ISSN 1010-2914.

In this paper the effectiveness of a fertilizer based algal species Caulerpa sertularoides with respect to commercial crops treated with chemical and organic fertilizers for the development of planting coriander (cilantro) was studied. The research corresponds to a field with an experimental design with control group: one control group, the second with the algal fertilizer , the third commercial chemical fertilizer and the fourth with commercial organic fertilizer, four cultures were performed . To test the efficacy of each fertilizer measures the number of stems and their height and leaf number were made. The results indicated a greater amount of algal culture stems and leaves larger than with chemical fertilizer. The algal fertilizer qualitative analysis was performed to establish the presence of heavy metals, resulting positive for mercury and arsenic.
